"The version of AOS installed on the remote host is prior to 6.5.6.5. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AOS-6.5.6.5 advisory.

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote
    attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the
    KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the
    protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG
    records. (CVE-2023-50387)

  - The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to
    it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to
    crash an application or overwrite a neighbouring variable. (CVE-2024-2961)

  - nscd: Stack-based buffer overflow in netgroup cache If the Name Service Cache Daemon's (nscd) fixed size
    cache is exhausted by client requests then a subsequent client request for netgroup data may result in a
    stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This
    vulnerability is only present in the nscd binary. (CVE-2024-33599)

  - nscd: Null pointer crashes after notfound response If the Name Service Cache Daemon's (nscd) cache fails
    to add a not-found netgroup response to the cache, the client request can result in a null pointer
    dereference. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability
    is only present in the nscd binary. (CVE-2024-33600)

  - nscd: netgroup cache may terminate daemon on memory allocation failure The Name Service Cache Daemon's
    (nscd) netgroup cache uses xmalloc or xrealloc and these functions may terminate the process due to a
    memory allocation failure resulting in a denial of service to the clients. The flaw was introduced in
    glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.
    (CVE-2024-33601)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
